Abstract

The invention discloses a vibration reduction device and a vehicle pipeline vibration reduction system. The vibration reduction device is used for connecting a fixing component with a vibration component and comprises a main body and a connection rod, wherein the main body comprises a fixing part connected with the fixing component and connection parts connected with the vibration component; a plurality of connection parts are arranged and are used for connecting a plurality of positions of the vibration component; at least one of the plurality of connection parts is connected with the connection rod and is connected with the vibration component through the connection rod; a damping mechanism is arranged between the connection part and the connection rod and is used for supplying damping force to the connection rod; vibration of the vibration component is transmitted to the damping mechanism through the connection rod along an axial direction; through cooperation of the connection rodand the damping mechanism, vibration energy of the vibration component can be gradually absorbed by the damping mechanism, so that the vibration reduction effect is achieved. The vehicle pipeline vibration reduction system comprises the vibration reduction device. The vibration reduction device is arranged in a vehicle pipeline; the vehicle pipeline forms the vibration component; and NVH performance of the vehicle can be improved.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction, and in particular relates to a vibration reduction device and a vehicle pipeline vibration reduction system. Background technique [0002] Installing a vibration damping device on the vibrating part is a common means of reducing vibration and noise. In the existing vibration damping device, there is usually only one fixed point on the vibrating part. When the vibrating part is long, the vibrating part is still prone to large The vibration of the vibration damping device cannot achieve the expected effect. [0003] For the engine, there are large thin-walled cavity parts in the pipeline parts of the engine, and the modal frequency is generally low, which is easy to be excited to generate noise, which directly affects the NVH performance of the engine and the vehicle. Therefore, through vibration reduction It is extremely necessary for the device to reduce the vibration of the pipeline...
